Title: Radar equipment
Inventor: OOKA SHUICHI
IPC: G01S13/524
Filed: 1991-01-08
Abstract: PURPOSE:To provide a radar equipment that can delete a fixed target even when a transmission frequency is changed for each transmission pulse. CONSTITUTION:The frequency of a sampling clock from a clock oscillator is converted into integer by a frequency synthesizer so as to form a reference signal, and the reference signal and a locally oscillated signal are mixed together by a mixer so as to form a transmission RF signal. The reflecting signal from a target received by an antenna is mixed with the locally oscillated signal by the mixer, and an IF signal is obtained, which is detected by a phase detector through the reference signal, and is formed into a video signal, which is A/D converted by a fixed target deleting circuit through the sampling clock, and this digital video signal is added to a signal for which the video signal is delayed by the transmission cycle, and a fixed target is thus deleted.

Title: Digital-to-analog connecting circuit
Inventor: KINOSHITA SEIJI
IPC: H03K5/007
Filed: 1980-04-07
Abstract: PURPOSE:To constitute this circuit so that a transient response is not generated in the interface with the analog circuit, by taking out a digital output from the tri-state gate, and always clamping its output terminal to an intermediate level. CONSTITUTION:The output terminal of the digital tri-state gate 4 is clamped to half voltage of the supply voltage VDD in advance. Accordingly, in case when there is no input signal A in the terminal A, the output signal E is VDD/2, if the input signal A is in an ''L'' level, the output signal E becomes an ''L'' level, and if the input signal A is in an ''H'' level, the output signal E becomes an ''H'' level. When this output signal E is taken out to the analog amplifier 2 through the capacitor 3, a transient phenomenon is generated, and it can be prevented that the zero potential is shifted.

Title: Wick type oil burning device
Inventor: SHIGEOKA TAKEHIKO
IPC: F23N5/20
Filed: 1982-03-19
Abstract: PURPOSE:To reduce the producing of hydrocarbon compound and odor at the cut-off of burning of the titled device by a method wherein a suction means of a igniting heater is still operated during a certain period after the cut-off of burning. CONSTITUTION:Just after the cut-off of burning, large amount of unburned gas still remains in a burning chamber 6. When a wick 3 is lowered by the burning cut-off operation, an igniting heater 8 and a fan 17 are simultaneously electrified and kept at electrified condition during designated period. The condition in said burning chamber 6 after the cut-off of burning is kept under negative pressure by the ejector effect produced by the air flow from said fan 17. Accordingly, the air is introduced into said burning chamber 6 from air openings 13 of an outer fine tray part 12 and air openings 14a of a burner 14. Thereby, whole space area of said ring-shaped burning chamber 6 is rapidly maintained at combustible condition. A flame ignited by said igniting heater 8 is instantly spread over whole space area inside of said burning chamber 6, the remaining unburned gas is burnt out. Thus, the producing of hydrocarbon compound and odor can be reduced.

Title: Ball transmission type differential limiting device
Inventor: NAKAMURA AKITOSHI
IPC: F16H48/12
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To provide a ball transmission type differential limiting device which can transmit power in such a way to gradually increase according to a difference of rotational speed. SOLUTION: When a rotational difference is generated between differential gear call and a ball disk 3, each ball 4 reciprocates in a groove of the differential gear case while rolling along a groove of the ball disk 3. When the rotational speed difference between differential gear case and the ball disk 3 become larger, resistance caused when each ball 4 rolls against a viscous fluid is increased, so that power is transmitted between differential case and the ball disk 3. In this case, since the resistance of the viscous fluid increases with a moving speed of each ball 4, power to be transmitted gradually increases according to the rotational difference.  A thrust washer, a part of the device, is made of alloy steel or a sintered material which are processed a surface treating such as carboized hardening, nitrided hardening, carbonitrizing hardening, and hard chrome plating or synthetics resin coating.
